OIL-CUP.

Specification of Letters Patent.

Application led February 15, 1918. Serial N o. 217,449.

To all whom t may concern.' i

Be it known that I, HERBERT BOLD, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a certain new and useful Improvement in Oil-Cups, of which the following is a specification.

rIhe present invention relates to oil cups, and more particularly to a device of that type adapted to cover an oil receiving opening and for closing the same after a quantity of oil has been injected into the opening.

An object of the present invention is to provide an oil cup of this character which comprises relatively few parts, which is provided with a single lateral opening and an improved means for closing the same and which may be opened by projecting a nozzle of an oil can through the opening, and provide an oil cup the opening thereof being closed by a single spring arranged within the oil cup and held in position therein in a novel manner.

The invention also aims at the provision of an oil cup having a spring shutter which may be formed relatively large to withstand constant use and which automatically closes the cup after a nozzle of an oil can has been withdrawn from the cup to insure the exclusion of dust, grit and the like, from the oil package.

The above, and various other objects and advantages of this invention will be in part described, and in part understood, from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a side elevation of an oil cup constructed according to the present invention.

Fig. 2 is a vertical section taken through the same in a plane intersecting the lateral opening in the cup.

Fig. 3 is a similar view taken axially at right angles to the showing in Fig. 2.

Fig. 4L is a top plan view of the cup.

Fig. 5 is a transverse section taken on a plane indicated by the line 5-5 of Fig. 2, and showing the lateral opening closed.

Fig. 6 is a longitudinal section taken through the cup in a plane intersecting the lateral opening, and showing a slight modification in the form of the cup and the spring.

Referring to this drawing, 10 designates a spud or coupling which may be of any suitable form, and which for the purpose of illustration is disposed as comprising an externally threaded plug adapted to be secured in a bearing or the like. The spud 10 may be provided near its upper end with an annular outstanding flange 11 having annularly disposed wrench receiving faces at its periphery, and which is rabbeted at its upper side and near its peripheral edge to form a shoulder 12 upon which is seated the open end of a cap or body part 13.

The cap 13 is preferably formed from spun or pressed sheet metal, is entirely closed at its upper end, and is threaded or otherwise suitably fixed uponA the upper end of the spud 10. The cap 13 is provided with a single lateral opening 14 of a size adapted to freely receive the nozzle of an oil can or the like therethrough for introducing oil into the cap for passage through the spud l0.

The opening 14 is adapted to be normally closed for excluding dust, grit, and the like, from the interior of the cup, and for eEectively closing the opening 141:, a spring 15 is employed. The spring 15 is preferably relatively broad and is bent substantially U-shaped with one arm longer than the other. The spring 15 is adapted to be sprung within the cap 13 with one of its broad arms bearing against the inner wall of the cap 13 over the opening 111 to close the opening. The other arm of the spring is adapted to engage against the inner wall of the cap 13 at a point diametrically opposite the opening 14 and thus hold the spring tight against the opening. As shown particularly in Figs. 2 and 5, the ends of the spring are preferably transversely curved to conform to the curvature of the inner wall of the cap 13 for effectively closing the opening 14 and supporting the spring within the cap. The free end of the spring 15 is preferably rolled inward to a slight extent to form a lip 16 adapted to freely slide over the end of the nozzle of the can and admit of the easy withdrawing of the nozzle without binding between the spring and the marginal edge of opening 14.

The spring 15 is anchored within the cap 13 to hold the spring from shifting circumferentially within the cap. This result is effected by forming the cap 13 at its closed end with a projection 17, which, as shown in the form illustrated in Fig. 2 they project outwardly from the cap 13 to form a transverse recess in the inner side of the cap for Patented Dec. 24, 1918.V

the reception of a correspondingly formed projection 1S at the intermediate portion ofj width of the spring 15 so as to freely receive the projection 18 of the spring therein. The projection 18 of the spring is preferably formed by bowing the spring laterally at its intermediate portion, and in the showing in Fig. 2, the spring is bowed outwardly to engage within the recess of the projection 17 of the cap.

ln Fig. 6, the projection 19 of the c ap projects inwardly and is interlocked with the projection 2O of the spring by extending into the concavity ofthe projection 20. In either instance, the spring is interlocked with the cap and is held from shifting in edgewise direction about the inner wall of the cap. The interlocking of the spring and the cap also holds the intermediate portion of the spring against the closed end` of the cap and thus insures the retention of the free end of the spring against the opening 14.

The projection 17 may be utilized for turning the cup into and out of position upon its bearing by engagement of a wrench or the like, against the projection 17, and the projection 19 may be utilized for the same purpose by using the blade of a screw driver or the like, which is adapted to enter the concavity of the inwardly pressed projection 19. The projection of the cap therefore, serves the purpose of anchoring the spring within the cap and also the purpose of interlocking with a suitable tool for placing and removing the cup.,

It will be noted that the spring is held in position without the use of rivets, slits or other devices, which tend to weaken the spring and the cap and which do not admit of the quick removal of the spring for adjusting the same. rThe device is relatively simple, comprises relatively few parts, and may be economically and easily manufactured. y

In use, it is only necessary to project the nozzle of an oil can or the like, through the opening 14 and against the free end of the spring 15. When the oil is injected into the cap it is only necessary to withdraw the nozzle wheny the free end of the spring snaps back into normal position and eifectively closes the opening 14. The long arm of the spring l5 preferably engages against the inner end of the spud 10 and serves to hold the projection of the spring and thecap in interlocking engagement and to also prevent the accidental longitudinal dislodgment of the free end of the spring. The intermediate portion of the spring 15 is preferably Hattened to lend flexibility to the spring and distribute the flexing action over a relatively cap secured at its open end over the screw plug and provided with an opening in one side, a substantially inverted U-shaped spring sprung into said cap With its ends engaging against the opposite sides thereof, one end of said spring closing said opening.

2. An oil cup comprising a hollow body having an openino'v in one side thereof, and a substantially U-s aped spring sprung into the body with its ends engaging against the opposite sides thereof and with one end engaging over the opening t0 close the same, said body and spring having interlocking projections adapted to maintain the spring in position for closing the opening.

3. An oil cup comprising a hollow body having an opening in one side thereof, and a spring arranged within the body with ends engaging against the opposite sides thereof and one end covering said opening, said body having a projection and said spring having a projection, said projections of the body and the spring adapted to interlock for holding the spring from shifting circumferentially in the body.

4. An oil cup comprising a spud, a cap secured at its open end'over the spud and provided with an opening in one side thereof for receiving the nozzle of an oil can, said cap having a projection at its' closed end, and a spring sprung into the cap with its ends bearing against the opposite sides thereof and with one end covering said opening, said spring having a projection adapted to interlook with the projection of the cap for holding the spring from shifting in the cap, and the free end of the spring being curled inward to form a lip adapted to slide freely over, the nozzle of the oil can as the latter is moved into and out of the opening.

5. An oil cup comprising a screw plug, a cap secured at its open end over said screw plug and provided with an opening in one side, a substantially inverted U-shaped spring sprung into. said cap with its ends engaging against the opposite sides thereof, one end of said spring closing said opening, and means to preventcircumferential movenient of the spring within the cap.
